YAW-300S constant loading pressure testing machine

The YAW-300S constant loading pressure testing machine adopts a servo motor to control the oil source, a high-precision digital micro valve, and a force closed-loop control function. It can achieve equal load rate loading or equal stress rate loading with high control accuracy and good reliability. Especially suitable for experimental sites that require long-term continuous work. This testing machine is an essential testing instrument for building materials, construction engineering, quality supervision, metrological testing, scientific research institutions and other units.

The product complies with the specific provisions for testing machines in GB/T17671-2021, JC/T960-2022, and JC/T724 standards.
